Description

  The present invention relates to a liquid crystal display device, and more particularly to a backlight assembly thereof.

  The liquid crystal display device displays a desired image on a screen by modulating transmitted light or reflected light for each pixel using the electro-optic effect of liquid crystal.

  In general, a liquid crystal display device includes a light source unit that applies light to liquid crystal in addition to a liquid crystal control unit that controls light modulation by liquid crystal. The liquid crystal control unit includes a liquid crystal display panel, and the light source unit includes a backlight assembly. In general, the backlight assembly is roughly classified into an edge type and a direct type depending on the installation location of the lamp. In the edge type backlight assembly, a light guide plate is installed behind the liquid crystal display panel, and a lamp is installed along the side surface of the light guide plate. The light from the lamp is uniformly applied to the entire back surface of the liquid crystal display panel through the light guide plate. In the direct type backlight assembly, a diffusion plate is installed behind the liquid crystal display panel, and a lamp is installed behind the diffusion plate. The light from the lamp is diffused by the diffusion plate and is uniformly applied to the entire back surface of the liquid crystal display panel.

  In the backlight assembly, a lamp socket is generally used to fix the lamp to the storage container. In particular, in a direct backlight assembly, in order to uniformly illuminate the entire surface of the liquid crystal display panel, a large number of lamps must be accurately and stably arranged in a certain pattern. Therefore, in the conventional direct type backlight assembly, the lamp socket to be connected to each lamp is once fixed to an alignment plate different from the storage container, and then the entire alignment plate is fixed to the storage container. In particular, the lamp socket is housed in the storage container through an insertion port formed in the storage container.

  In the conventional backlight assembly, since the alignment plate is used for fixing the lamp socket to the storage container, it is difficult to further simplify the assembly process of the liquid crystal display device. In addition, since separate molds are required for the lamp socket and the alignment plate, it is difficult to further reduce the manufacturing cost. In addition, since foreign substances are likely to enter the gap between the lamp socket and the alignment plate, it is difficult to further improve the positioning accuracy of the lamp socket. In addition, since the arrangement of the lamp sockets differs depending on the type of liquid crystal display device, a different alignment plate must be manufactured for each type of liquid crystal display device. Thereby, it is difficult to further reduce the manufacturing cost and the manufacturing time.

  An object of the present invention is to enable a lamp socket to be accurately fixed to a storage container without using an alignment plate, thereby enabling further reduction in the number of parts and further simplification and automation of the manufacturing process. To provide a light unit.

  The backlight assembly according to the present invention includes a lamp including a lamp electrode, a lamp socket that supports the lamp electrode, an inverter that supplies power to the lamp, and a storage container that houses the lamp socket and the inverter. The storage container preferably includes a socket insertion portion that directly supports the lamp socket at a position facing the end portion of the lamp, and an inverter storage portion that stores the inverter. The socket insertion portion is preferably formed at the upper end of the first side wall of the storage container extending along one side of the bottom surface of the storage container, more preferably along the long side of the bottom surface. The socket insertion portion further preferably includes a recess formed at the upper end of the first side wall. A lamp socket is inserted into the recess. The recess preferably includes a step portion extending in the depth direction on the inner surface in contact with the surface of the lamp socket. The lamp socket is inserted into the socket insertion portion so as to slide along the stepped portion. On the other hand, the inverter housing part is preferably formed on the side opposite to the socket insertion part with the first side wall therebetween.

  The storage container preferably includes a separation bar protruding in a direction perpendicular to the bottom surface from the upper end of the first side wall. The socket insertion portion and the inverter storage portion are preferably separated by a separation bar. In addition, the upper end of the first side wall may include a partition wall that extends in the horizontal direction with respect to the bottom surface along the first side wall between the socket insertion portion and the inverter housing portion. A space connecting the socket insertion portion and the inverter storage portion may be narrowed by the partition wall.

  Unlike the conventional backlight assembly according to the present invention, the lamp socket is directly and stably fixed to the storage container without using an alignment plate. In particular, since the lamp socket mounting process can be automated, the assembly process of the backlight assembly is further simplified, and the process time can be further shortened. As a result, the manufacturing cost of the liquid crystal display panel can be further reduced.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

The entire surface of the common electrode display panel 124 is covered with a common electrode, and the boundary portion of each pixel is shielded from light by a black matrix. Since both the pixel electrode and the common electrode are transparent, light incident from the back surface of the thin film transistor display panel 123 is transmitted through each pixel and emitted from the front surface of the common electrode display panel 124.

  Preferably, since the thin film transistor display panel 123 is wider than the common electrode display panel 124, the end portions along one long side and one short side of the thin film transistor display panel 123 protrude outside the common electrode display panel 124. .

The reflection sheet 134 is preferably made of a highly reflective material, and reflects light emitted backward (downward in FIG. 1) from each lamp 133 toward the back of the liquid crystal panel 126 (upward in FIG. 1). Thereby, the light loss of the lamp 133 is minimized.

  The diffusing plate 132 is preferably rectangular, and is disposed in front of each lamp 133 (upward in FIG. 1) at a certain distance from each lamp 133. The diffusion plate 132 diffuses the light incident on the back surface from each lamp 133 and emits the light forward from the entire front surface with uniform intensity.

  The optical sheet 131 is disposed in front of the diffusion plate 132 (upward in FIG. 1), and preferably includes a diffusion sheet, a first prism sheet, and a second prism sheet.

The step portion 31 is preferably a groove extending in the vertical direction, that is, in the depth direction of the socket insertion portion 30. By sliding the lamp socket 20 in the vertical direction along the step portion 31, the lamp socket 20 can be easily inserted into the socket insertion portion 30. Further, since the lamp socket 20 and the socket insertion portion 30 can be directly adhered without a gap, the lamp socket 20 can be stably fixed to the storage container 100.

  Although not shown in FIGS. 6 and 7, a hook portion, that is, a hook-shaped protrusion may be provided on the inner surface of the socket insertion portion 30. When the lamp socket 20 is inserted into the socket insertion portion 30, the hook portion engages with the side surface of the lamp socket 20.

The interval between the holes 45a in the bottom surface 45 is preferably constant. In addition, the interval between the holes 45a may be narrowed in a range facing the portion of the inverter 50 that generates a large amount of heat.

  As shown in FIG. 2, a separation bar 32 is preferably provided between each socket insertion portion 30 and the other part of the storage container 100.
